Use of infantFS and FS in the interval 2 - 4.5 years of age
by Michelangelo Fabbrizzi 11 Jan '24

11 Jan '24

External Email - Use Caution Dear FS experts, I see it is recommended to use infantFS below 2 years of age, whereas FS has been used for 4.5 years and above. I was wondering what could be used in the interval 2 - 4.5 years of age: which are benefits and drawbacks of both? Thanks, appreciated, Mic

Inter-rater reliability
by Taylor, Lisa 10 Jan '24

10 Jan '24

External Email - Use Caution Hi there, Has anyone in this community used a form of inter-rater reliability measure for multiple people editing for one project? I have some PIs who are interested in doing this for a project where several labs will be editing Freesurfer for a project. I am a bit stumped as I have always just used visual review to ensure reliability/validity between editors. Also, would a inter-rater reliability measure be more effective than visual reviewing? Thank you for any insight you can provide! Lisa

Re: [Freesurfer] Freeview keeps aborting.

External Email - Use Caution  I would check with your IT support staff about the error including asking if the machines in your cluster are setup to display X Windows sessions with image viewing applications like Freeview.   If the machines support remote graphics, they should be able to tell you what you need to set in your terminal session for it to work.   But it could be they expect programs like freeview to run on your local client machine and read the image files/data over the network via NFS, etc. - R.

Scratch Directory Permissions Denied
by Michael Ruvalcaba 09 Jan '24

09 Jan '24

External Email - Use Caution Hello, I am trying to run the recon -all function in my MATLAB pipeline using Freesurfer 6.0.0 and I have no issues with it. However, when I run the recon -all step using Freesurfer 7.2.0 and run the following command (the recon -all step finishes without error by the way): ft_read_mri([subdir '3D_Images/freesurfer_pre-op/freesurfer/mri/T1.mgz']); I get the following error: /bin/bash: /scratch/tp746feb5d_1e83_4141_b25d_1824a1cb209e.load_mgh.m.mgh: Permission denied The issue is there is no scratch file and it looks like between version 6.0.0 and 7.2.0 there is some extra lines of code that uses a scratch directory (which 6.0.0 doesn't) Does anyone have any input on this? I hope this made sense! Best, Michael Ruvalcaba

[WARNING: ATTACHMENT UNSCANNED]FreeSurfer Error
by ERNEST KISSI 09 Jan '24

09 Jan '24

External Email - Use Caution Dear Freesurfer Developers, I am a graduate student working on Macromolecular Proton Fraction (MPF) and I need to generate parcellation for it using Freesurfer. I have read several articles that reported successful results with this method. However, I have encountered some errors when I tried to run Freesurfer on my data. Some of the errors are related to transformation at the talairach, and some are related to missing brain mask. I have been struggling with these issues for four days and I have not been able to process any of my data. I have an urgent deadline for my thesis presentation on Friday and I would appreciate your assistance. I have subscribed to the mailing list but I have not received a confirmation email yet. I have attached a screenshot of my registration and two examples of my T1 MPF images. Could you please test them on your end and let me know what the problem is and how to fix it? Thank you for your time and support. Sincerely,

recon-all vs. recon-all-clinical: missing ROIs
by Biondo, Francesca 09 Jan '24

09 Jan '24

External Email - Use Caution Hi, recon-all generates these volumes, amongst others: "Left-vessel", "Left-choroid-plexus", "Right-vessel", "Right-choroid-plexus" recon-all-clinical does not generate these volumes. Or at least that I am able to detect. Any ideas how to extract or calculate them? Regarding the choroid plexus, would it be correct to use this formula? Estimated choroid plexus volume (both left and right) = "VentricleChoroidVol" - "left lateral ventricle" - "right lateral ventricle" Thank you very much for your support - Francesca

Re: [Freesurfer] conversion of D-K atlas
by Fischl, Bruce R.,PHD 09 Jan '24

09 Jan '24

Hi Anna Parcellation is more than just format conversion - you need to map it onto the details of an individual subject's anatomy. In addition, the DKT atlas is only cortical. If you want subcortical regions in addition you should run recon-all as it will produce both. Cheers Bruce From: Arkhipova Anna, MUDr. <Anna.Arkhipova(a)fnol.cz> Sent: Tuesday, January 9, 2024 6:14 AM To: Freesurfer(a)nmr.mgh.harvard.edu; fischl <fischl(a)nmr.mgh.harvard.edu> Cc: phlustik(a)upol.cz Subject: conversion of D-K atlas External Email - Use Caution Dear prof. Fischl, We would like to kindly ask a question, if there is a way to convert Fressurfer Atlas Desikan-Killiany (lh and rh.curvature.buckner40.filled.desikan_killiany.2010-03-25.gcs) to Nifti file for parcellation of our resting-state fMRI data. Although we have tried script mri_convert, we obtained only cortical regions, but we need also subcortical regions. Would it be anyhow possible? Thank you so much in advance. Sincerely yours, Anna Arkhipova, MD fMRI laboratory Department of Neurology, Faculty of Medicine and Dentistry Palacky University and University hospital Olomouc Czech Republic

SynthSR for T2-weighted images
by hmarzban＠student.ubc.ca 09 Jan '24

09 Jan '24

External Email - Use Caution Hello Eugenio, I wanted to inquire whether you have plans to create a tool for synthesizing T2-weighted low-field MRI images similar to SynthSR, which was developed for T1-weighted images. I'm in need of synthesizing T2-weighted images for Hyperfine, and I'm curious if there is a suitable method available for this purpose. Because, as I understand it, SynthSR transforms T2-weighted images into T1-weighted ones, and it is not designed for handling T2-weighted images. Is my understanding correct? Regards Hengameh
